I cannot answer your question exactly but I would look at how herring bone floors patterns are laid down. Those usually have a tongue and groove and I think that they only attach the tongue side to the subfloor with nails and no glue. They often have bevels along the edges so that any gap that form from shrinkage won't be as obvious and the tongue also helps to hide the gap. Note that you need the tongues and grooves and also bevels if you go that route on the ends too. In a way, it probably works a little like a ship lap backing on the back of a cabinet.
